Evo-Stik Evo-Plast is a concentrated liquid waterproofing plasticiser for use with cement mortar mixes for external renderings as an aid in Dry harling, Pebble dashing, Rough casting, and similar finishes. The improvement in workability of rendering is made possible by the entrainment of air which greatly reduces the internal friction within the mix between cement & sand particles. The improvement in waterproofing is sufficient to offer long term protection against dampness and driving rain.
